摘要：A cascaded sigma-delta analog to digital converter (300) comprising a firstsigma-delta modulator (310) having an input configured to receive an input signal, asecond sigma-delta modulator (320) configured to receive an error signal from the firstmodulator and a noise filter (230) configured to receive an output signal from each of thefirst and second modulators and to provide a modulated and filtered output signal,wherein the analog to digital converter comprises an adder (216) configured to providethe error signal from the first modulator by combining an output signal from a loop filter(212) of the first modulator with the input signal.
